Metal Working Machine Operatives Salary — UK & US Data (2025)

What This Job Involves

Set up and operate a variety of machine tools to produce precision parts and instruments out of metal. Includes precision instrument makers who fabricate, modify, or repair mechanical instruments. May also fabricate and modify parts to make or repair machine tools or maintain industrial machines, applying knowledge of mechanics, mathematics, metal properties, layout, and machining procedures.

Typical duties, per the US Department of Labor's O*NET occupational database (mapped to this role's closest US equivalent, Machinists):

• Calculate dimensions or tolerances, using instruments, such as micrometers or vernier calipers.
• Machine parts to specifications, using machine tools, such as lathes, milling machines, shapers, or grinders.
• Measure, examine, or test completed units to check for defects and ensure conformance to specifications, using precision instruments, such as micrometers.
• Set up, adjust, or operate basic or specialized machine tools used to perform precision machining operations.
• Program computers or electronic instruments, such as numerically controlled machine tools.
• Study sample parts, blueprints, drawings, or engineering information to determine methods or sequences of operations needed to fabricate products.

Salary in Context

Within process, plant & machine operatives as a whole (19 occupations tracked on this site), metal working machine operatives pays about 3% above the average median for the category, ranking 6 of 19 by median pay. That's useful context if you're weighing this role against a lateral move within the same broad field, rather than against occupations with a completely different pay structure.

Location makes a real difference here: London pays around 39% more than North East for this same occupation, based on the regional breakdown above. If you're able to work remotely or are open to relocating, that gap is often larger than a typical annual pay rise.

The spread between the 25th and 75th percentile — roughly the band most people in this role actually fall into — is about 47%. A narrower spread suggests pay for this role is fairly standardised across employers; a wider one suggests more room to negotiate, or a role where employer type and seniority matter more than average.

US Salary Overview

In the United States, the equivalent occupation (Machinists, SOC 51-4041) has a national median wage of $58,750 per year according to BLS Occupational Employment and Wage Statistics (May 2025). Around 287,000 people are employed in this occupation in the US. Figures are shown in local currency and are not converted.

What Affects Pay for Metal Working Machine Operatives, and How to Use This Data When Negotiating

The figures above describe the market, not any one employer's ceiling. A few things generally explain where an individual lands within that range:

• Location: Pay for the same job title can vary by tens of thousands depending on region or state — see the location breakdown on this page for this specific role.
• Experience level: The gap between the 10th and 90th percentile mostly reflects years of experience and seniority within the role, rather than employer generosity alone.
• Employer size and sector: Larger organisations and higher-paying sectors tend to sit above the median for a given role; smaller employers and some non-profit or public-sector employers often sit below it.
• Qualifications and certifications: Professional qualifications relevant to a role can shift where someone lands within the percentile range, particularly in regulated or technical occupations.
• How common the role is: Roles with fewer people employed nationally tend to show wider pay variation than high-volume occupations, simply because the underlying sample is smaller and less standardised.

If you're using this page to prepare for a pay conversation, a few practical steps:

• Bring the actual percentile figures from this page into the conversation — a specific, sourced number ("the median for this role is £X") carries more weight than a general sense that you're underpaid.
• If you have several years of experience or a scarce skill set, anchor to the 75th percentile rather than the median — the median describes the middle of the market, not where an experienced hire should expect to land.
• Use the regional or state figure, not the national one, if your employer benchmarks pay nationally but you're based in a higher-paying area — the location breakdown above is the more relevant number to quote.
• Treat total compensation, not just base salary, as the real comparison — pension contributions, bonus structure and benefits can close a gap that base pay alone doesn't show.
• Time the conversation around a review cycle or a clear recent win, and bring both arguments — the market-rate evidence on this page and your own contribution — together rather than either alone.

Where This Data Comes From

The UK figures on this page come from the Office for National Statistics' Annual Survey of Hours and Earnings (ASHE), the UK government's official annual employer survey of pay — not a self-reported salary site, and not a jobs-board average of advertised (rather than actually paid) salaries. The US figures come from the Bureau of Labor Statistics' Occupational Employment and Wage Statistics (OES) programme, the US equivalent: a large-scale survey of employers rather than job seekers. Both are gross figures — before income tax, National Insurance, or US federal/state tax and FICA — for the reason that gross pay is what's actually comparable across employers and locations; take-home pay depends on each person's own tax situation.

UK occupations are classified under the Standard Occupational Classification (SOC) 2020, and US occupations under the equivalent US SOC system — the two classification systems don't map perfectly onto each other, so where this page shows a UK and a US occupation together, that pairing is our own editorial best match for the closest equivalent role, not an official government cross-reference.
